The M&P design has an improved trigger and enhanced ergonomics that allow for end-user customization. An industry standard picatinny rail and a higher grip has been afforded with an improved grip and beavertail. Many of the ergonomic study elements that had been incorporated into the Sigma and the Smith & Wesson SW99 were brought over to the M&P. The improved trigger weight and feel and the unique takedown method (not requiring a dry-fire pull of the trigger) were meant to set the M&P apart from the popular Glock pistols.
